S. de Wet (UCT) and P.J. Groot (Radboud/UCT/SAAO) report on behalf of the
MeerLICHT consortium:
Following the detection by Swift of GRB 221202A and its X-ray counterpart
(Caputo et al., GCN 33005), the 0.6m wide-field MeerLICHT telescope,
located at Sutherland, South Africa, obtained 5x300s observations in the
q,z,i,r,g bands beginning at 21:14:34 UT on 2022 December 2, approximately
1.14 hours after the Swift trigger.
We detect no new source at the XRT position (Caputo et al., GCN 33005) in
any of our images down to the following 3-sigma upper limits, in the AB
magnitude system:
q > 21.80 at 21:17:27 UT
z > 20.01 at 21:22:34 UT
i > 21.02 at 21:28:03 UT
r > 21.53 at 21:33:25 UT
g > 21.58 at 21:38:54 UT
MeerLICHT is built and run by a consortium consisting of Radboud
University, University of Cape Town, the South African Astronomical
Observatory, the University of Oxford, the University of Manchester and the
University of Amsterdam.
